How to use translation to change colors in SimpleMarket

In your ad for SimpleMarket, you write:

"This theme has been localized for easy translation. Using the theme’s MO and PO and a newly included .pot file, you can quickly translate the design without having to hunt through the theme’s PHP files to change each word."

Could you please give a specific example as to how I could use translation to change the pea green to royal blue throughout the entire site?
